Here is an assembly video from KAMAX. It is their HMX250CB. This is an off road enduro, but they do have one with lights (same one!)... But it shows the overall construction quality. I wish we had an importer.

As shown on the alibaba listing, that is indeed the Zongshen ZS172FMM-3A like we get in the Templar M and Templar base models. Zongshen allows client branding on their engines (like this one has). I like the way he just tilts the frame forward to connect the lower linkage on the rear shock.
